Supports age-related gastrovascular reflex attenuation; hypothesis-generating for postprandial hemodynamic changes in elderly, needing longitudinal confirmation.
Does the gastrovascular reflex (increase in muscle sympathetic nerve activity and blood pressure during gastric distension) attenuate in normal ageing?
The gastrovascular reflex, characterized by an increase in muscle sympathetic nerve activity during gastric distension, is attenuated in healthy elderly individuals compared to young individuals.
Orshoven et al. (2004) studied this question.
